COMBINED TYPE'WRITING AND COMPUTING MACHINE.

Specification of Letters Patent.

Patented Dec. 14., 1915.

Application flied November 21, 1912. Serial'No. 732,626.

To. all whom it may concern:

Be it known that we, Gos'ravn 0. Deer;- .NER and JOSHUA E. DAVIDSON, residin in the city, county, and State of New ork,

both citizens of the Unite'd States, have invented certain new and useful Improvements in Combined Type-Writing andCom-' aspecification. p

This invention relatesto combined type writing and computing machines, and is herein illustrated as applied to a combined typewriting and computing machine of the Underwood-Wright type in which the numeral keys pfthe typewriter cause computing wheels to be engaged seriatz'm by a mas ter' wheel and to be turned thereby to an extions of totali'zers, and said totalizers are tent determined by the numeral keys of the typewriter. The computing wheels are grouped in a gang or gangs whichform porarranged to be adjustably mounted on a totalizer carriage, whichicarriagemoves step-by-step with the typewriter carriage and is adjustably connected thereto. Said totalizer, carriage may comprise a chan- 'neledbar having-a flat: upper surface on which the frames of the 'totalizers'may rest.

' said channelv to'steady the 'totalizei's. On

Each totalizer may comprise a bib or extension, which has atongue'arranged to enter the bib may be mounted a locking member arranged to enter openings in said channeled bar and catch back of said openings, these openings being spaced at definite interva-ls or distances apart, which bear a definite; predetermined relation to the wheels or computing members of the totalizers, so

. that the positions of the openings correspond to those of theaforesaid computing members. 'Said lock'may comprise a cam v for positively drawing the bib of the totalwar against said channeled bar, so as to hold the totalizer positively in place. The totalizer carriage may also comprise a rack bar which has stops set on it, and a bar pivoted on the typewriter carriage may be arranged to engage any of said stops at will' and thus couple the two carriages together and cause them to travel in unison.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 represents so much of the front of an Underwood-Wright combined typewriting and adding machine as is sufficient for the understanding of our invention. Fig. 2' is a. perspective view of a totalizer and the channeled bar to which it is fastened. Fig. 3 is keys, through a clutch 2 causes a. master wheel shaft 3 to rotate either backwardly or forwardly, so that a master wheel4 thereon may turn the dial or computing wheel 44 within the totalizer 5 with which the master wheel engages. Said master wheel shaft is journaled in the frame at the right hand of the machine, and adjacent the master wheel, it extends into a sleeve 6- of an arbor 7; said arbor extending to the left hand side of the machine where it enters an upright 8.0n the frame and is held thereon in position by means of a pin 9 against which the end of the arbor bears, said pin being retained in position by means of a spring 10 fastened to said upright 8 by a screw 11. By i'emoving the pin 9, it will be seen that the arbor'7 can be withdrawn from within any totalizer through which it may be extending} form ing as itdoes the extension of the master wheel shaft, whereupon such totalizer may readily be removed from the machine.

The totalizers 5, of which there are four shown in Fig. 1, the right hand one being broken away, comprise casings 12 having fiat bottoms 13, which rest on the fiat upper surface 14 of a channeled bar '15. Each totalizer comprises an extension 16 in the form-of a bib which overlaps the front of the channeled bar. Each bib has thereon a tongue 17 which enters within said channeled bar-and bears-against a wall 18 formed as a bar rabbeted into both the upper and the lower members of said channeled bar. Said bar 18 is provided with openings 19 which 1, controlled in its turning by thenumeral are vertically elongated and rounded at their ends, and are arranged to allow a T-shaped locking member 0 to pass therethrough, and 'then to be turned transversely so that its head 21 then bears against the inner surface of the bar 18.. Each locking member .20 incl des the transverse T-head 21 and the stem 22, which stem has pivoted thereon at its Outer end a handle 23 comprising a lock ing cam face 24 arranged, when the handle is turned in one direction parallel to the face of the locking bar, to bear against the bib 16 and so draw the T-head- 21 forward against the internal face of the bar 18 and so positively lock the bib to said bar. The earn 24 does not bear directly on the bib 16. but against a circular plate 25. sunk in a depression of said i and. having a tongue 26 extending across a lrerf in the stem 22, against which kerf the cam 24 isarranged to bear. as seen in Fig. 3. For the pur ose of bearing in this manner. the handle 23 is pivoted so that it lies and swings within said kerf.

In locking theloclring member 20, by means of the cam 24. the plate 25 is'moved against the tension of a cone spring 27 lving within a pocket in the bib 16 surrounding the lock ng mem er 0 T e plate 25 has cut from its periphery a segment 28. and throuah the segment projects a pin 29 ar ranged to strike the ends of said se ment Whenever the handle rotates the locking member and the plate to one side or the other, and thus said pin limits the amount of throw of said handle sidewise. Said segment has its ends so cut that when one end is in contact with the pin 29, the T-head 21 of the locking member 20 will pass freely through the opening 19. while if the other end of. said segment is in contact with said pin 29. the T-head-lies squarely across the opening 19. The spring 27, it will be observed. positivelv loosens the arts whenever the handle 23 is swung to, releasing position. The sides of the tongue 17, it will be noted. lie close against the upper and lower members of the channeled bar 15. and thus coiinerate with the bottom 13 of the totalizer in Mining it.

The channeled bar 15 forms part of a totalizer carriage which also comprises a top bar 30 and ends 3. and 32-and slides on upper and lower guide rails 37 and 38 fast in brackets at the ends of the tvnewriter frame. Said top bar 30 is adiustable between said ends 31 and 32. which ends are fast to the channeled bar 15; and said'bar 30 comprises a. rack 33 on which stops 34 can be set at lettor-space intervals corresponding to the pitch of the letter-feed of the typewriter. The totalizer carria e is adapted to be driven bv said stops 34 by means of an arm 35, pivoted at 36 on the typewriter carriage, so as to travel therewith.

ing wheels bv the-master wheel.

It will be noted that by means of the openings 19, the various totalizers can be separately adjusted on the totalizer carriage, and that by means of the stops 34 and the rack 33, the totalizer carriage can be adjusted as a whole relatively to the typewriter carriage. In this connection, it may be stated that there is a definite correspondence between the arrangement of the openings 19 and the computing wheels 44, or, in other words, a predetermined relation between the spaces or intervals at which the openings are arranged, and the positions of the computing wheels 44. This is a matter of extreme importance, for the reason that inasmuch as the master wheel moves successively from one computing wheel to the one-of next higher order. such movement must be preserved for all positions of the totalizer, so as to insure proper actuation of the com ut- Furthermore. since the openings 19 are located at regular intervals. the bar.15 wherein they are formed constitutes, in effect, a rack. in the broad meaning! of that term, as will be understood. It will also be seen that thelocking members 20 are iournaled in openinns 40 in the bib 16 and so a e held each in its bib bv means of the T-heads 21. There are. therefore. no parts that would become detached whenever a totalizer is removed from the machine, and the lockingmember being provided with elongated openings spaced at definite intervals corresponding v to the intervals of the computing members of the totalizer, an extension on said total- 7 izer lv ng against the face of said bar. and I o latch comprising an elongated head arranged to be inserted interchangeably through any one of said openings when at izer, an extension on said totalizer lying against the face of said bar, a latch on said extension, an abutment on said latch arranged to be inserted interchangeably through any one of said openings when attaching the totalizer, to exactly locate said totalizer on said bar, and to be turned transversely to the opening to lock said totalizer to said bar, and a spring drawing said abutment against said bar,'said abutment being withdrawable from said opening when detaching the totalizer.
